Ladies and Gentlemen, I give you the most beautiful replacement for the Sunny 1200 that is a direct swap for, at the moment that I know of, ANY A series engine. The Wilson 70-25-12272.

It is a diesel boat generator platform, heavy duty meant for continuous and stressfull use. The blue wire is for a tachometer, fully internal regulated and has an LR connector. It has been pre-treated with salt resistance, including all interior mechanical and electrical components. The mounting and fitment is 100% perfect on my A12 engine, top mounted. Pulley lines up without any need to change the length of the belt (960-990mm), and there is above-nominal clearance for the fan.

There is a 90 amp alternator version, the LR190. I had O-o-o...oreilysssssssssssssss autoFARTS order it to compare the sizing. There are quite a few variations of the 90 amp, therefore a bit more difficult to get the right one. I don't recommend that.

I've purchased the 12v 80 amp version. Other part numbers it goes by are as follows: Lr180-03 Lr180-03C 112375 4-6278 LR180-03A LR180-03B 119573-77200

If you're looking for a replacement alternator for LR135 series that is a direct swap, check this 80 Amp out.

Final update; this swap works perfectly, output is clean and expected for a marine/industrial alternator. Zero modifications needed, completely bolt in. You can add an alternator tacho if you're feeling sassy.
